Long term occupational exposure to solvent mixtures may cause adverse effects to the central nervous system with neurobehavioral symptoms. And some organic slovents have been suggested to cause impairment of tuberoinfundibular dopaminergic activity and neurochemical mechanisms controlling pituitary secretion. For the purpose of assessing neuroendocrine effects in occupational solvents exposure, hormonal study settings (shoes-manufacturing industry & fishing products industry) and compared with nonexposed controls(33 men, 85 women). Male workers exposed to solvent mixtures had significantly lower plasma level of follicle-stimulating hormone(FSH) than nonexposed male controls. While female workers exposed to solvent mixtures had significantly lower plasma levels of growth hormone(GH), and thyroid-stimulating hormone(TSH) than nonexposed female controls. The results of significant decrease in plasma concentrations of pituitary hormones(FSH, GH, and TSH) in workers exposed solvent mixtures indicate that occupational exposure to solvent mixtures may induce neuroendocrine effects through an effect on hypothalamic pituitary axis.

Vascular lesions of the oral and maxillofacial area is interesting to clinicians because it is difficult in management and has poor prognosis. There have been attempt to classify vascular lesion and recently new classification is introduced that have two basic entities, 1) hemangioma, 2) vascular malformation. It is useful that evaluation of lesion, treatment planning and predicting on prognosis. But vascular lesion is still difficult to clinicians about treatment. A case of acidic cell carcinoma combined with hypervascularity arising on the hard palate in a 28-year-old woman is reported. We mistook it for vascular lesion because of hypervascularity. The clinical and histologic feature are described. Literatures about neovascularization of tumor & acidic cell carcinoma are reviewd, too. And we attempt to solve the problem of hypervascularity.

For each construction material used, there is certain theoretical limit in sizes. For tall building construction, the reduction in slab weight is the first step to take in order to break such size limits. In this paper, the feasibility of such objective is proven and given by numerical analysis result. For a typical building slab, both concrete and advanced composite sandwich panels are considered. The concrete slab is treated as special orthotropic plate to obtain more accurate result. Any method may be used to obtain the deflection influence surfaces needed for this vibration analysis. Finite difference method is used for this purpose, in this paper. The influence of the modulus of the foundation on the natural frequency is thoroughly studied.

As the society system becomes industrialized and urbanized, most seniors have been excluded from laboring and social participating compulsorily or voluntarily. Further more, the trend toward the nuclear family initiated by young generation has taken away even the role of them and gave them much leisure time. This leisure time is not the one which is given in the social and family role, but the one which is spent in vain without any given role. The purpose of this dissertation is to identify the effect of sport program for senior citizens in their leisure and life satisfaction. To achieve this purpose, the correlation between the existence of participation in the life sports and the leisure satisfaction of seniors and the correlation between the higher degree of participation in the life sports. The major findings obtained from this study were following. First, it found that participants in sport for all program of older persons showed greater leisure satisfaction than non-participants Second, the higher the frequency and duration of participation in sport for all program, the higher leisure satisfaction. Based upon these findings and within limitations of this study, it was concluded that participation in sport for all program of older persons would increase the leisure satisfaction.

This study was conducted to develop a simple selection method for herbicide-resistance weeds. Two methods, designated "seedling method" and "stem node method" were employed for screening of barnyardgrass against propanil and butachlor. In the seedling method, shoot and root growth of barnyardgrass were significantly inhibited at quarter of the recommended herbicide rate, while in the stem node method, the similar inhibition was obtained at half of the recommended rate. Thus, it was concluded that the seedling method is more simple and quick method to evaluate response of barnyardgrass to propanil and butachlor compared to stem node method.

There is no doubt that good nutrition for infants relates not only to the health of the individual but also influences the health of the nation. In spite of nutrition's trememdous importance, there is no data available concerning infant nutrition and, moreover, there is no study about the knowledge, attitudes and practies of infant feeding and weaing. Taking into account the fact that most infants in Korea are breast fed, and have a long lactation period, there must be provision for adequate supplemental food at the proper time. The first step in launching a new health program should be the exact evaluation of the present status of infants' feeding diet. This study was designed to collect basic data on the status of infants' nutrition in order that these data might be sued as program organization indicators for the improvement of infant nutrition. The data were obtained through interviewing 726 mothers who registered their children at the Taegu MCH Center's well baby clinic.

본 연구에서는 발육기에 있는 남자 초등학생 3학년을 대상으로 태권도 수련기간에 따라 초등학생의 신체조성 및 하지 등속성근기능을 비교하여 규칙적인 운동의 생활화에 대한 중요성을 인식시켜주는데 그 목적이 있으며, 연구대상은 B광역시 K구 소재 태권도 체육관에서 수련을 하고 있는 남자 초등학생 3학년을 대상으로 태권도 수련기간이 3-10개월(STG) 14명, 14-20개월 16명(MTG), 24개월 이상 15명(LTG)으로 나누어 실시하였다. 자료처리는 SPSS Ver. 18.0을 이용하여 측정항목의 평균값(M)과 표준편차(SD)를 산출하여, 수련기간에 따른 변화를 알아보기 위해 one-way ANOVA를 실시하였고, 사후검증은 Duncan을 실시하였으며, α=.05로 설정하였다. 신체조성에서는 모든 그룹간 유의한 차이가 없었고, 하지 등속성 근기능은 STG와 LTG에서 오른쪽, 왼쪽 모두 신전근과 굴곡근에서 유의한 차이가 나타났다. 이상의 결과를 종합해 볼 때 남자 초등학생의 태권도 수련기간이 길수록 하지근력이 우수한 것으로 나타났다.
